As shown in Fig. 3 (a), Fig. 3 (b), head position guiding mechanism 30 has the leaf spring 31 to the+directions X application of force to the side 8a of flat board member 8.As shown in Fig. 3 (b), leaf spring 31 is Japanese " く " word shape, and one end is fixed on the sidewall 3a of head supporting frame 3.Joggling part and side 8a butt, keep the state to the+directions X application of force to side 8a.

If the phantom of Fig. 4 (a) is that as shown in Fig. 4 (b), head position guiding mechanism 30 has movable member 32.Movable member 32 has the roughly shape of square column, at formation inclined plane, its underpart 32a.The thickness that inclined plane 32a makes movable member 32 on+directions X from Fig. 4 above tilt to attenuation downward.

The width of the angle of inclination of the inclined plane 32a of movable member 32 and the above-below direction of inclined plane 32a in Fig. 4 is according to pressing component 33 described later is set to ± amount of movement that directions X moves.That is, the angle of inclination hour of inclined plane 32a, pressing component 33 diminishes to the amount of movement of ± directions X, and the angle of inclination of inclined plane 32a is when large, and pressing component 33 is large to the mobile quantitative change of ± directions X.And when the width of the above-below direction of inclined plane 32a in Fig. 4 is narrow, pressing component 33 diminishes to the amount of movement of ± directions X, and the width of the above-below direction of inclined plane 32a in Fig. 4 is when wide, and pressing component 33 is large to the mobile quantitative change of ± directions X.

As shown in Fig. 4 (b), head position guiding mechanism 30 has pressing component 33 (abutting part of the present invention).Pressing component 33 is configured between the side 8b of flat board member 8 and the inclined plane 32a of movable member 32, has the contact-making surface 33a contacting with inclined plane 32a and the press surface 33b that presses side 8b.Contact-making surface 33a and inclined plane 32a configure abreast, and contact with inclined plane 32a face.Press surface 33b is its whole the plane contacting with side 8b face.

As shown in Fig. 4 (b), head position guiding mechanism 30 has makes movable member 32 in ± travel mechanism 34 that Z direction moves.Screwed hole 32b, the bottom that travel mechanism 34 comprises along Z direction the top that is located at movable member 32 has the bolt 36 of the screw 36a screwing with screwed hole 32b and restriction bolt 36 at ± limiting part 37 that Z direction moves.

Be provided with one group of rib 36b on the top of bolt 36.Limiting part 37 has square tube shape, is configured between head supporting frame 3 and head 2, and is fixed on the sidewall 3b of head supporting frame 3.Limiting part 37 surrounds the movable member 32 of square column shape, rotates to limit movable member 32.And limiting part 37 has the opening 37a that the lower end for movable member 32 is passed through in its underpart, so that movable member 32 can move to-Z direction.And limiting part 37 has the hole connecting for bolt 36 at an upper portion thereof, and have and be sandwiched in one group of top board 37b between rib 36b.

If the phantom of Fig. 4 (a) is as shown in Fig. 4 (c), head position guiding mechanism 30 has the engaging support mechanism 35 that movable member 32 and pressing component 33 are fastened mutually.Engaging support mechanism 35 comprises the slit 33c being located on pressing component 33 and is located at the pin 32c on movable member 32.Slit 33c and inclined plane 32a extend setting abreast.Pin 32c can be chimeric with slit 33c movably in slit 33c.

The slit length of slit 33c is according to pressing component 33 is set at ± amount of movement that directions X moves.That is, in short-term, pressing component 33 diminishes to the amount of movement of ± directions X slit length, and slit length is when long, and pressing component 33 is large to the mobile quantitative change of ± directions X.Inclined plane 32a and contact-making surface 33a are set to contact with each other in the moving range of the pressing component 33 being stipulated by slit length.

According to this structure, by manual rotation bolt 36, can adjust as described below the position of head 2 on directions X.When bolt 36 is rotated, the length of the part mutually screwing of the screw 36a of bolt 36 and the screwed hole 32b of movable member 32 changes.Bolt 36 is because of the movement of be limited ± Z of the fastening direction of one group of rib 36b and top board 37b, when therefore the length that screws part of screw 36a and screwed hole 32b changes, only has movable member 32 to move up and down in Fig. 4 along ± Z direction.Specifically, when the length that screws part of screw 36a and screwed hole 32b reduces, movable member 32 moves to-Z direction, and the length that screws part of screw 36a and screwed hole 32b is while increasing, and movable member 32 moves to+Z direction.Now, movable member 32 fastens by engaging support mechanism 35 and pressing component 33, and is surrounded by the limiting part 37 of square tube shape, and therefore its rotation is limited.So, when bolt 36 is rotated, by travel mechanism 34, movable member 32 moves in ± Z direction.

When movable member 32 moves along+Z direction, inclined plane 32a is moved upward, therefore movable member 32 and the less thick of positions pressing component 33 butts on directions X.On the other hand, pressing component 33 is owing to being pressed to+directions X by leaf spring 31 via flat board member 8, therefore pressing component 33 with flat board member 8 to the direction interlock contacting that keeps in touch face 33a and inclined plane 32a.Thereby pressing component 33 and flat board member 8 all move to+directions X.Now, the pin 32c being located on movable member 32 moves to the top that tilts in the slit 33c of pressing component 33.Thus, can adjust to+directions X the position of head 2.

While movement along-Z direction due to movable member 32, inclined plane 32a moves downwards, and therefore movable member 32 the thickness on directions X becomes large with positions pressing component 33 butts.Therefore, pressing component 33 is pressed to-directions X, pressing component 33 and resist the active force of leaf spring 31 and move to-directions X with the flat board member 8 of its butt.Now, the pin 32c being located on movable member 32 moves to the below that tilts in the slit 33c of pressing component 33.Thus, can adjust to-directions X the position of head 2.

At this, flat board member 8, owing to being clamped by benchmark abutting part 70 and leaf spring 71, therefore keeps side 8d and benchmark abutting part 70 to support ground state mobile.Thereby flat board member 8 makes side 8d along benchmark abutting part 70 and moves along directions X.So, benchmark abutting part 70 and leaf spring 71 have the function that makes the guiding part that flat board member 8 moves along directions X.

In the time carrying out the adjustment of above position, 33 of pressing components are pressed side 8b, because both can phase mutual friction not cause pressing component 33, the second side 8b abrasion, therefore can carry out the adjustment of high-precision position.And, as long as the active force of leaf spring 31 guarantees head 2 to press required enough sizes to pressing component 33.Therefore, dwindle the active force of leaf spring 31, can carry out by less power the movement of movable member 32, easily carry out thus small position adjustment.Thereby can carry out high accuracy and trickle position adjustment to head 2.And, use the slit 33c that extends abreast with inclined plane 32a and the pin 32c chimeric with this slit 33c, movable member 32 and pressing component 33 are fastened mutually, can make thus pressing component 33 not move to the direction of depart from ± directions X.

Turn back to Fig. 3 (a), on head supporting frame 3, on each head 2, be fixed with and at ± directions X, head 2 carried out to the different direction different with ± directions X of the head position guiding mechanism 30 of position adjustment is carried out position adjustment head position guiding mechanism 40 to head 2.

Head position guiding mechanism 40 has leaf spring 41 and pressing component 43 (abutting part of the present invention).Leaf spring 41 has Japanese " く " word shape, and one end is fixed on the sidewall 3c of head supporting frame 3.The side 8c butt of joggling part and flat board member 8, keeps the state to the+Y-direction application of force to side 8c.Pressing component 43 has Japanese " コ " word shape in top view, presses the position identical with leaf spring 41 on the directions X of side 8d to-Y-direction.

Head position guiding mechanism 40 has the structure identical with head position guiding mechanism 30 and is used as the structure that pressing component 43 is moved., with movable member 32, travel mechanism 34 and the limiting part 37 of head position guiding mechanism 30 have in the same manner with the movable member of pressing component 43 butts, make movable member ± travel mechanism that Z side moves up and the limiting part of restriction movable member rotation.But the movable member of head position guiding mechanism 40 sides is along with moving to ± upper the direction of Z and pressing component 43 being moved to ± Y-direction.Along with pressing component 43 moves in ± Y-direction, move to ± Y-direction the end (right part in Fig. 3 (a)) of the flat board member 8 of being pressed to pressing component 43 by leaf spring 41.On the other hand, the end (left part in Fig. 3 (a)) of the side that the side with pressing component 43 butts of flat board member 8 is contrary is owing to being pressed by benchmark abutting part 70, therefore flat board member 8 take with the abutment of benchmark abutting part 70 as fulcrum rotation.,, centered by the axle of the vertical direction along by this abutment, move in the mode of drawing arc.Thus, head 2 shown in Fig. 3 (a) ± θ side adjusts upward position.Rotating to be along the rotation of the face 2a that spues of ± θ direction, the face 2a that can make to spue is rotated along horizontal direction.

By the head position guiding mechanism 40 that on be combined in ± directions X, head 2 is carried out the head position guiding mechanism 30 of position adjustment and in ± θ direction, head 2 carried out to position adjustment, can carry out position adjustment to head 2 in the desirable position in XY plane.At this, XY plane is the plane by directions X and Y-direction regulation.

In the time of assembling printer 1 and while changing head, head 2 is mounted on the head supporting frame 3 that is fixed with

position adjusting mechanism

30 and 40 or on bracing frame 3, is removed from the head.For example, when head 2 is assembled to head supporting frame 3, carry out in the horizontal direction behind location to a certain degree with respect to head supporting frame 3, as shown in Figure 5, make head 2 move to head supporting frame 3 from top.Then, press down the main part 2b of head 2 until arrive the position being supported on support component 72.Thus, the flat board member 8 of main part 2b is supported on support component 72 in vertical direction, and is supported by the each several part of the head position guiding mechanisms 30 such as leaf spring 31, leaf spring 71, pressing component 33, the each several part of head position guiding mechanism 40 in the horizontal direction.

On the other hand, ink

flow path pipe

51 and 52 is connected with

auxiliary reservoir unit

23 and 24 from top.Due to ink flow

path pipe

51 and 52 from protuberance 2c towards vertical below, therefore head 2 can be installed to head supporting frame 3 from top time, ink

flow path pipe

51 and 52 is connected to auxiliary reservoir unit 23 and 24.Ink

flow path pipe

51 and 52 is located at 2 the outstanding protuberance 2c of main part 2b from the head and goes up, and separates from main part 2b.Therefore, connect

auxiliary reservoir unit

23 and 24 and the operation of ink

flow path pipe

51 and 52 become easy.

Head 2 is mounted to head supporting frame 3, ink

flow path pipe

51 and 52 and is also connected to auxiliary reservoir unit 23 and at 24 o'clock, by head

position guiding mechanism

30 and 40 is operated, and the horizontal level of fine setting head 2.Thus, head 2 is configured to desirable position in the horizontal direction.

According to present embodiment described above, the end of the opposition side of the ink

flow path pipe

51 and 52 being connected with

auxiliary reservoir unit

23 and 24 on directions X disposes head position guiding mechanism 30 and 40.Therefore, the part being connected with

auxiliary reservoir unit

23 and 24 of head 2 is difficult to disturb with head

position guiding mechanism

30 and 40, easily carries out position adjustment.

And, use head position guiding mechanism 40 in the time that ± θ side adjusts upward the position of head 2, benchmark abutting part 70 becomes fulcrum in rotary moving with the position of head 2 butts.Because benchmark abutting part 70 is configured near ink

flow path pipe

51 and 52, therefore, in the time that ± θ side adjusts upward the position of head 2, avoid ink

flow path pipe

51 and 52 and produced larger movement.Thereby, suppressed position and adjusted to ink flow

path pipe

51 and 52 and the impact that brings of the coupling part of

auxiliary reservoir unit

23 and 24.

And ink

flow path pipe

51 and 52 along vertical direction is ± rotary middle spindle of θ direction.Suppose that ink

flow path pipe

51 and 52 for example extends in the horizontal direction, ink

flow path pipe

51 and 52 more separates from rotating shaft the closer to front end.Therefore, head 2, in the time that ± θ side rotates up, exists ink

flow path pipe

51 and 52 to give birth to all the more the possibility of larger movement the closer to front end.With respect to this, ink

flow path pipe

51 and 52 is during along rotary middle spindle, and the front end of ink

flow path pipe

51 and 52 can not separate from rotating shaft, has therefore suppressed front end larger movement occurs.And, because the direction along rotary middle spindle is the direction orthogonal with the direction of handling ink

flow path pipe

51 and 52, though therefore head 2 ± θ side rotates up, also can suppress ink

flow path pipe

51 and 52 and come off from auxiliary reservoir unit 23 and 24.So, in the present embodiment, suppressed position and adjusted to ink flow

path pipe

51 and 52 and the impact that brings of the coupling part of

auxiliary reservoir unit

23 and 24.

And no matter be to use head position guiding mechanism 30 or use 40 to carry out position adjustment, benchmark abutting part 70 all forms with the position of head 2 butts the benchmark that position is adjusted.Therefore, the benchmark of position adjustment is difficult to depart from, and can stably carry out the adjustment of desirable position.
